Twenty-one people have been charged with dealing drugs on and around college campuses after a multi-year federal investigation uncovered a drug ring involving students at three North Carolina universities, CNN reported.

U.S. Attorney Matthew Martin said that those arrested were accused of dealing drugs in and around the University of North Carolina-Chapel Hill, Duke University and Appalachian State University campuses.
Members of several fraternities were charged, with more arrests to potentially come.
According to court records, the UNC chapters of Phi Gamma Delta, Kappa Sigma and Beta Theta Pi are involved in illegal drug activity.
The drugs involved include cocaine, LSD and marijuana. And the drug proceeds exceed $1.5 million, according to the Drug Enforcement Administration.
“These fraternity members’ drug trafficking crimes contributed to a toxic and dangerous environment on these college campuses,” DEA Special Agent in Charge Robert Murphy said. “The arrest of these drug traffickers makes these college campuses and their respective communities safer.”
Eight of the charged had pleaded guilty to at least one charge, CNN reported.
Kappa Sigma’s national organization said it will investigate the allegations internally.
